Rowing and its associated training can be a strenuous activity. Therefore, you should be in good health and have no medical or physical condition precluding heavy exercise. If there is any doubt, you should first consult your doctor. Some conditions, such as asthma and diabetes, for example, do not prevent individuals participating in this sport, but you do have a duty to declare any condition that puts yourself or others at risk. It is important, therefore, that you inform coaches and crew members of any condition that they may have to deal with in the event of an emergency.
